UM OneDrive#

The University of Manitoba provides Microsoft OneDrive to its users as part of the Microsoft Office 365 contract. While not suited, for performance reasons, for online computation work or for storing large datasets, OneDrive can be a useful storage space to store important data of smaller size, documents, articles and such. It also offers some data preservation features like data recovery and data history.

Please also refer to UM Data Security Classification to learn which kinds of data can be stored where.

rclone is a universal tool for uploading and downloading data to and from a wide variety of cloud storage systems. In particular, it is the tool for transferring data between a Linux HPC system and the Microsoft OneDrive.

However, due to the nature of Web-storage like OneDrive, needs for MFA, etc. a configuration step is required to make rclone on Grex connect to the OneDrive. The configuration step requires access to a Web browser.

Configuring Rclone for OneDrive on Grex#

Please login to Grex’s OpenOnDemand portal and request a “Simplified Desktop” session. The desktop session is required to do the Web-based part of OneDrive authentication; however, main configuration is done in the command line because rclone is a command line tool.

When the Desktop session is ready, connect to it in OOD’s Desktop tab, and open a terminal. Run the following commands:

module spider rclone
module load rclone
rclone config

The last command shows a prompt and will ask a large number of interactive questions. Answer them as follows:

• Q: “No remotes found – make a new one”
  • answer “n” for a new remote
• Q: “name>”
  • call it “OneDrive”
• Q: “Storage>”
  • From the numbered list of storage, pick the number corresponding to “Microsoft OneDrive”. The numbers change version to version. As of now, ‘31’.
• Q: “client_id>”
  • leave blank (press Enter)
• Q: “client_secret>”
  • leave blank (press Enter)
• Q: “Edit advanced config?”
  • answer “n” for No
• Q: “Use auto config?”
  • answer “y” for Yes
• at this point, a browser window will pop up. Not every browser works, so we recommend Firefox (firefox command in the terminal) to be used as the default browser. Please inspect the browser window and URL to see if it looks like an authentic UManitoba login page!
  • Authenticate using your UManitoba email and UManitoba credentials and MFA.
  • Go back to your terminal when “Success” is displayed.
• Q: “Your Choice>”
  • type a number to use your business OneDrive (as of now, ‘1’)
• Q: “Choose drive to use>”
  • type ‘0’
• Q: “Is this ok y/n>”
  • answer “y” to confirm the drive selection
• Q: “y/e/d>”
  • answer “y” to confirm adding the remote to rclone

If the configuration was successful, at this point an OneDrive access token has been created under your home directory, valid for a number of days (90 days). You can start using command line rclone tools from any SSH session on Grex. When the token expires, it can be regenerated with rclone config reconnect remote: command.

Using Rclone for data transfers#

The command line rclone tool should be available, so as usual for the Grex software , its module should be loaded. Then rclone ls command can be used to explore your OneDrive, and rclone copy to copy the files to and from OneDrive as per the example below:

module load rclone
rclone ls OneDrive:/
rclone copy myfile.txt OneDrive:/testdir
rclone ls OneDrive:/testdir
rclone copy OneDrive:/testdir/myfile.txt myfile.bak

Please refer to rclone Documentation for more information. Rclone is an universal data transfer tool that can be used for a variety of storages, and OneDrive is just one application for it.

Using Rclone in OOD#

On Grex, OpenOnDemand supports Rclone connection within the File App automatically. The Rclone folder will appear for the user after he performs the above rclone config step. As with the command line access, the access token has to be periodically refreshed.
